Rapidly evolving genes and stress adaptation of two desert poplars, Populus euphratica and P. pruinosa [PDF]

open access: yes, 2013
Understanding which genes have evolved rapidly with the recent tree speciation in arid habitats can provide valuable insights into different adaptation mechanisms. We employed a comparative evolutionary analysis of expressed sequence tags (ESTs) from two

Cooperation With Arbuscular Mycorrhizal Fungi Increases Plant Nutrient Uptake and Improves Defenses Against Insects

open access: yesFrontiers in Ecology and Evolution, 2022
Plants have evolved various defense mechanisms to cope with biotic and abiotic stresses. Cooperation with microorganisms, especially arbuscular mycorrhizal fungi (AMF), strengthens the defense capabilities of host plants.

Beyond EICA : understanding post-establishment evolution requires a broader evaluation of potential selection pressures [PDF]

open access: yes, 2011
Research on post-establishment evolution in nonnative plant populations has focused almost exclusively on testing the Evolution of Increased Competitive Ability (EICA) hypothesis, which posits that the lack of specialized herbivores in the invaded range ...

Genome-wide characterization of the sorghum JAZ gene family and their responses to phytohormone treatments and aphid infestation

open access: yesScientific Reports, 2022
Jasmonate ZIM-domain (JAZ) proteins are the key repressors of the jasmonic acid (JA) signal transduction pathway and play a crucial role in stress-related defense, phytohormone crosstalk and modulation of the growth-defense tradeoff.

Ethylene, ACC, and the Plant Growth-Promoting Enzyme ACC Deaminase

open access: yesBiology, 2023
Here, a brief summary of the biosynthesis of 1-aminocyclopropane-1-carboxylate (ACC) and ethylene in plants, as well as overviews of how ACC and ethylene act as signaling molecules in plants, is presented.

Toward a Molecular Understanding of Plant Hormone Actions [PDF]

open access: yes, 2016
Plants rely on a diverse set of small-molecule hormones to regulate every aspect of their biological processes including development, growth, and adaptation. Since the discovery of the first plant hormone, auxin, hormones have always been at the frontier

Excision Dominates Pseudogenization During Fractionation After Whole Genome Duplication and in Gene Loss After Speciation in Plants

open access: yesFrontiers in Genetics, 2020
We take advantage of synteny blocks, the analytical construct enabled at the evolutionary moment of speciation or polyploidization, to follow the independent loss of duplicate genes in two sister species or the loss through fractionation of syntenic ...

Evolutionary radiations in the species-rich mountain genus Saxifraga L.

open access: yesBMC Evolutionary Biology, 2017
Background A large number of taxa have undergone evolutionary radiations in mountainous areas, rendering alpine systems particularly suitable to study the extrinsic and intrinsic factors that have shaped diversification patterns in plants.

Welwitschia: Phylogeography of a living fossil, diversified within a desert refuge

open access: yesScientific Reports, 2021
Welwitschia mirabilis is one of the most extraordinary plant species on earth. With a fossil record of 112 My and phylogenetically isolated within the order Gnetales, the monotypic genus Welwitschia has survived only in the northern Namib Desert in ...
